This invention was made with government support under grant numbersMH082867 and MH087965, awarded by the National Institutes of Health. TheU.S. government has certain rights in the invention.

BACKGROUND

Alzheimer's disease (AD) is a neurodegenerative disease affecting theelderly, which results in progressive impairment of memory, languageskills and severe behavioral deficits. Hallmarks of the disease includedegeneration of cholinergic neurons in the cerebral cortex, hippocampus,basal forebrain and other regions of the brain important for memory andcognition. Other hallmarks of AD include neurofibrillary tanglescomposed of hyperphosphorylated tau and accumulation of amyloid βpeptide (Aβ). Aβ is a 39-43 amino acid peptide produced in the brain byproteolytic processing of β-amyloid precursor protein (APP) by theβ-amyloid cleaving enzyme (BACE) and gamma secretase which leads toaccumulation of Aβ in the brain, where Aβ 1-40 and 1-42 are theprincipal aggregate-forming species of Aβ.

Schizophrenia is a debilitating psychiatric disorder characterized by acombination of negative (blunted affect, withdrawal, anhedonia) andpositive (paranoia, hallucinations, delusions) symptoms as well asmarked cognitive deficits. While schizophrenia remains an idiopathicdisorder, it appears to be produced by a complex interaction ofbiological, environmental, and genetic factors. Over 40 years ago it wasfound that phencyclidine (PCP) induces a psychotic state in humans thatis very similar to that observed in schizophrenic patients. The findingthat the main mode of action of PCP is that of a non-competitiveantagonist of the N-methyl-D-aspartate (NMDA) subtype of ionotropicglutamate receptor stimulated a series of studies that have led to thedevelopment of the NMDA receptor hypofunction model of schizophrenia.Besides schizophrenia, dysfunction of glutamatergic pathways has beenimplicated in a number of disease states in the human central nervoussystem (CNS) including cognitive deficits, dementias, Parkinson'sdisease, Alzheimer's disease and bipolar disorder.

NMDA receptor function can be modulated by activation of GProtein-Coupled Receptors (GPCRs) that are known to physically and/orfunctionally interact with the NMDA receptor. The NMDA receptorhypofunction hypothesis is a proposal to explain the underlying cause ofschizophrenia. According to this hypothesis, any agent that canpotentiate NMDA receptor currents, either directly by action onmodulatory sites on the NMDA receptor (e.g., the glycine co-agonistbinding site) or indirectly by activation of GPCRs known to potentiateNMDA receptor function (e.g. the M₁ mAChR), has the potential toameliorate the symptoms of schizophrenia. In both preclinical and inclinical studies, Xanomeline, an M₁/M₄ preferring orthosteric agonisthas proved efficacious with regard to positive, negative and cognitivesymptoms, indicating that M₁ activation is a reasonable approach to thetreatment of schizophrenia. More recently, the selective M₁ allostericagonist TBPB demonstrated efficacy in multiple preclinical models ofschizophrenia.

Positive allosteric modulators are compounds that bind to a target, suchas a receptor, and can enhance the affinity or efficacy of anorthosteric agonist. For example, a selective muscarinic M₁ positiveallosteric modulator would preferentially bind to the muscarinic M₁receptor which would result in an increased affinity at that receptorfor acetylcholine (ACh), the endogenous agonist for the muscarinic M₁receptor, or an increase in the efficacy induced by ACh. In somesystems, the compound may also have an intrinsic activity to activatethe receptor in the absence of orthosteric ligand. As another example, adual M₁/M₄ positive allosteric modulator would induce a potentiatingeffect at both the M₁ and M₄ muscarinic receptors, but not necessarilyto an identical extent at both receptors. Positive allosteric modulation(potentiation), therefore, can be an attractive mechanism for enhancingappropriate physiological receptor activation.

Cholinergic neurotransmission involves the activation of nicotinicacetylcholine receptors (nAChRs) or the muscarinic acetylcholinereceptors (mAChRs) by the binding of the endogenous orthosteric agonistacetylcholine (ACh). Acetylcholinesterase inhibitors, which inhibit thehydrolysis of ACh, have been approved in the United States for use inthe palliative, but not disease-modifying, treatment of the cognitivedeficits in AD patients. An alternative approach to pharmacologicallyincrease the effects of ACh could be accomplished through the use ofpositive allosteric modulators either alone or possibly in combinationwith other mAChR agonists. mAChRs are widely expressed throughout thebody. The mAChRs are members of the family A GPCRs and include fivesubtypes, designated M₁-M₅. M₁, M₃ and M₅ mainly couple to Gq andactivate phospholipase C whereas M₂ and M₄ mainly couple to G_(i/o) andassociated effector systems. These five distinct mAChR subtypes havebeen identified in the mammalian central nervous system where they areprevalent and differentially expressed. M₁-M₅ mAChRs have varying rolesin cognitive, sensory, motor and autonomic functions. Activation ofvarious muscarinic receptors, particularly the M₁ subtype, has beenproposed as a mechanism to enhance cognition in disorders such as AD.Thus, without wishing to be bound by theory, it is believed thatselective positive allosteric modulators of mAChR subtypes that regulateprocesses involved in cognitive function could prove superior to AChEinhibitors for treatment of AD and related disorders as it is postulatedthat these compounds would exhibit improved selectivity for specificmAChRs

Evidence suggests that the most prominent adverse effects of AChEinhibitors and other cholinergic agents are mediated by activation ofperipheral M₂ and M₃ mAChRs and include bradycardia, GI distress,excessive salivation, and sweating. In contrast, M₁ has been viewed asthe most likely subtype for mediating the effects on cognition,attention mechanisms, and sensory processing. Because of this,considerable effort has been focused on developing selective M₁ agonistsand positive allosteric modulators for the treatment of AD.Unfortunately, these efforts have been largely unsuccessful because ofan inability to develop compounds that are highly selective for the M₁mAChR. Because of this, mAChR agonists that have been tested in clinicalstudies induce the same adverse effects of AChE inhibitors by activationof peripheral mAChRs. To fully understand the physiological roles ofindividual mAChR subtypes and to further explore the therapeutic utilityof mACh receptors in AD and other disorders, it can be important todevelop compounds that are highly selective positive allostericmodulators of M₁ and other individual mAChR subtypes.

Previous attempts to develop activators that are highly selective forindividual mAChR subtypes have failed because of the high conservationof the orthosteric ACh binding site. To circumvent problems associatedwith targeting the highly conserved orthosteric ACh site, a number ofgroups have shifted their focus to developing compounds that act atallosteric sites on mAChRs that are removed from the orthosteric siteand are less highly conserved. This approach is proving to be successfulin developing selective ligands for multiple GPCR subtypes. In the caseof mAChRs, a major goal has been to develop allosteric ligands thatselectively increase activity of M₁ or other mAChR subtypes. Allostericactivators can include allosteric agonists, that act at a site removedfrom the orthosteric site to directly activate the receptor in theabsence of ACh as well as positive allosteric modulators (PAMs), whichdo not activate the receptor directly but potentiate activation of thereceptor by the endogenous orthosteric agonist ACh. Also, it is possiblefor a single molecule to have both allosteric potentiator and allostericagonist activity.

Phase III trials have shown that orthosteric mAChR activators can haveefficacy in improving cognitive performance in AD patients. Moreover,data indicate that administration of M₁ activators decreases behavioraldisturbances, including delusions, hallucinations, outbursts, and othersymptoms in patients suffering from neurodegenerative diseases such asAlzheimer's disease. However, dose limiting adverse effects that may bedue to lack of M₁ mAChR selectivity led to failed launches of previousM₁ agonists. In some cases, evidence suggests that mAChR activation alsohas the potential to be disease-modifying in that these agents may lowerAβ in AD patients. Interestingly, the M₁-selective allosteric agonistTBPB was found to display effects on the processing of APP toward thenon-amyloidogenic pathway and decrease Aβ 1-40 and 1-42 production invitro. These data suggest that selective activation of M₁ may provide anovel approach for both symptomatic and disease modifying the treatmentof Alzheimer's disease.

Despite advances in muscarinic receptor (mAChR) research, there is stilla scarcity of compounds that are potent, efficacious and selectivepositive allosteric modulators of the M₁ mAChR that are also effectivein the treatment of neurological and psychiatric disorders associatedwith cholinergic activity, or other neurologic diseases in which themuscarinic M₁ receptor may be involved. These needs and other needs areaddressed by the present invention.

References in the specification and concluding claims to parts by weightof a particular element or component in a composition denotes the weightrelationship between the element or component and any other elements orcomponents in the composition or article for which a part by weight isexpressed. Thus, in a compound containing 2 parts by weight of componentX and 5 parts by weight component Y, X and Y are present at a weightratio of 2:5, and are present in such ratio regardless of whetheradditional components are contained in the compound.

A weight percent (wt. %) of a component, unless specifically stated tothe contrary, is based on the total weight of the formulation orcomposition in which the component is included.

As used herein, the terms “optional” or “optionally” means that thesubsequently described event or circumstance can or cannot occur, andthat the description includes instances where said event or circumstanceoccurs and instances where it does not.

As used herein, the term “allosteric site” refers to a ligand bindingsite that is topographically distinct from the orthosteric binding site.

As used herein, the term “modulator” refers to a molecular entity (e.g.,but not limited to, a ligand and a disclosed compound) that modulatesthe activity of the target receptor protein.

As used herein, the term “ligand” refers to a natural or syntheticmolecular entity that is capable of associating or binding to a receptorto form a complex and mediate, prevent or modify a biological effect.Thus, the term “ligand” encompasses allosteric modulators, inhibitors,activators, agonists, antagonists, natural substrates and analogs ofnatural substrates.

As used herein, the terms “natural ligand” and “endogenous ligand” areused interchangeably, and refer to a naturally occurring ligand, foundin nature, which binds to a receptor.

As used herein, the term “orthosteric site” refers to the primarybinding site on a receptor that is recognized by the endogenous ligandor agonist for that receptor. For example, the orthosteric site in themAChR M₁ receptor is the site that acetylcholine binds.

As used herein, the term “mAChR M₁ receptor positive allostericmodulator” refers to any exogenously administered compound or agent thatdirectly or indirectly augments the activity of the mAChR M₁ receptor inthe presence or in the absence of acetylcholine, or another agonist, inan animal, in particular a mammal, for example a human. In one aspect, amAChR M₁ receptor positive allosteric modulator increases the activityof the mAChR M₁ receptor in a cell in the presence of extracellularacetylcholine. The cell can be Chinese hamster ovary (CHO-K1) cellstransfected with human mAChR M₁. The cell can be Chinese hamster ovary(CHO-K1) cells transfected with rat mAChR M₁ receptor. The cell can beChinese hamster ovary (CHO-K1) cells transfected with a mammalian mAChRM₁. The term “mAChR M₁ receptor positive allosteric modulator” includesa compound that is a “mAChR M₁ receptor allosteric potentiator” or a“mAChR M₁ receptor allosteric agonist,” as well as a compound that hasmixed activity comprising pharmacology of both a “mAChR M₁ receptorallosteric potentiator” and a “mAChR M₁ receptor allosteric agonist”.The term “mAChR M₁ receptor positive allosteric modulator also includesa compound that is a “mAChR M₁ receptor allosteric enhancer.”

As used herein, the term “mAChR M₁ receptor allosteric potentiator”refers to any exogenously administered compound or agent that directlyor indirectly augments the response produced by the endogenous ligand(such as acetylcholine) when the endogenous ligand binds to theorthosteric site of the mAChR M₁ receptor in an animal, in particular amammal, for example a human. The mAChR M₁ receptor allostericpotentiator binds to a site other than the orthosteric site, that is, anallosteric site, and positively augments the response of the receptor toan agonist or the endogenous ligand. In one aspect, an allostericpotentiator does not induce desensitization of the receptor, activity ofa compound as a mAChR M₁ receptor allosteric potentiator providesadvantages over the use of a pure mAChR M₁ receptor orthosteric agonist.Such advantages can include, for example, increased safety margin,higher tolerability, diminished potential for abuse, and reducedtoxicity.

As used herein, the term “mAChR M₁ receptor allosteric enhancer” refersto any exogenously administered compound or agent that directly orindirectly augments the response produced by the endogenous ligand (suchas acetylcholine) in an animal, in particular a mammal, for example ahuman. In one aspect, the allosteric enhancer increases the affinity ofthe natural ligand or agonist for the orthosteric site. In anotheraspect, an allosteric enhancer increases the agonist efficacy. The mAChRM₁ receptor allosteric potentiator binds to a site other than theorthosteric site, that is, an allosteric site, and positively augmentsthe response of the receptor to an agonist or the endogenous ligand. Anallosteric enhancer has no effect on the receptor by itself and requiresthe presence of an agonist or the natural ligand to realize a receptoreffect.

As used herein, the term “mAChR M₁ receptor allosteric agonist” refersto any exogenously administered compound or agent that directlyactivates the activity of the mAChR M₁ receptor in the absence of theendogenous ligand (such as acetylcholine) in an animal, in particular amammal, for example a human. The mAChR M₁ receptor allosteric agonistbinds to a site that is distinct from the orthosteric acetylcholine siteof the mAChR M₁ receptor and activates the binding of an agonist or thenatural ligand to the orthosteric site of the mAChR M₁ receptor. Becauseit does not require the presence of the endogenous ligand, activity of acompound as a mAChR M₁ receptor allosteric agonist provides advantagesover the use of a pure mAChR M₁ receptor allosteric potentiator, such asmore rapid onset of action.

As used herein, the term “mAChR M₁ receptor neutral allosteric ligand”refers to any exogenously administered compound or agent that binds toan allosteric site without affecting the binding or function of agonistsor the natural ligand at the orthosteric site in an animal, inparticular a mammal, for example a human. However, a neutral allostericligand can block the action of other allosteric modulators that act viathe same site.

As used herein, the term “subject” can be a vertebrate, such as amammal, a fish, a bird, a reptile, or an amphibian. Thus, the subject ofthe herein disclosed methods can be a human, non-human primate, horse,pig, rabbit, dog, sheep, goat, cow, cat, guinea pig or rodent.

As used herein, the term “diagnosed” means having been subjected to aphysical examination by a person of skill, for example, a physician, andfound to have a condition that can be diagnosed or treated by thecompounds, compositions, or methods disclosed herein. For example,“diagnosed with a disorder treatable by modulation of mAChR M₁” meanshaving been subjected to a physical examination by a person of skill,for example, a physician, and found to have a condition that can bediagnosed or treated by a compound or composition that can modulatemAChR M₁. As a further example, “diagnosed with a need for modulation ofmAChR M₁” refers to having been subjected to a physical examination by aperson of skill, for example, a physician, and found to have a conditioncharacterized by mAChR M₁ activity. Such a diagnosis can be in referenceto a disorder, such as a neurodegenerative disease, and the like, asdiscussed herein. For example, the term “diagnosed with a need forpositive allosteric modulation of muscarinic acetylcholine receptoractivity” refers to having been subjected to a physical examination by aperson of skill, for example, a physician, and found to have a conditionthat can be diagnosed or treated by positive allosteric modulation ofmuscarinic acetylcholine receptor activity. For example, “diagnosed witha need for partial agonism of muscarinic acetylcholine receptoractivity” means having been subjected to a physical examination by aperson of skill, for example, a physician, and found to have a conditionthat can be diagnosed or treated by partial agonism of muscarinicacetylcholine receptor activity. For example, “diagnosed with a need fortreatment of one or more neurological and/or psychiatric disorderassociated with acetylcholine dysfunction” means having been subjectedto a physical examination by a person of skill, for example, aphysician, and found to have one or more neurological and/or psychiatricdisorder associated with acetycholine dysfunction.

As used herein, the phrase “identified to be in need of treatment for adisorder,” or the like, refers to selection of a subject based upon needfor treatment of the disorder. For example, a subject can be identifiedas having a need for treatment of a disorder (e.g., a disorder relatedto mAChR M₁ activity) based upon an earlier diagnosis by a person ofskill and thereafter subjected to treatment for the disorder. It iscontemplated that the identification can, in one aspect, be performed bya person different from the person making the diagnosis. It is alsocontemplated, in a further aspect, that the administration can beperformed by one who subsequently performed the administration.

As used herein, the terms “administering” and “administration” refer toany method of providing a pharmaceutical preparation to a subject. Suchmethods are well known to those skilled in the art and include, but arenot limited to, oral administration, transdermal administration,administration by inhalation, nasal administration, topicaladministration, intravaginal administration, ophthalmic administration,intraaural administration, intracerebral administration, rectaladministration, sublingual administration, buccal administration, andparenteral administration, including injectable such as intravenousadministration, intra-arterial administration, intramuscularadministration, and subcutaneous administration. Administration can becontinuous or intermittent. In various aspects, a preparation can beadministered therapeutically; that is, administered to treat an existingdisease or condition. In further various aspects, a preparation can beadministered prophylactically; that is, administered for prevention of adisease or condition.

The term “contacting” as used herein refers to bringing a disclosedcompound and a cell, a target receptor (e.g. a muscarinic acetylcholinereceptor), or other biological entity together in such a manner that thecompound can affect the activity of the target, either directly; i.e.,by interacting with the target itself, or indirectly; i.e., byinteracting with another molecule, co-factor, factor, or protein onwhich the activity of the target is dependent.

As used herein, the terms “effective amount” and “amount effective”refer to an amount that is sufficient to achieve the desired result orto have an effect on an undesired condition. For example, a“therapeutically effective amount” refers to an amount that issufficient to achieve the desired therapeutic result or to have aneffect on undesired symptoms, but is generally insufficient to causeadverse side effects. The specific therapeutically effective dose levelfor any particular patient will depend upon a variety of factorsincluding the disorder being treated and the severity of the disorder;the specific composition employed; the age, body weight, general health,sex and diet of the patient; the time of administration; the route ofadministration; the rate of excretion of the specific compound employed;the duration of the treatment; drugs used in combination or coincidentalwith the specific compound employed and like factors well known in themedical arts. For example, it is well within the skill of the art tostart doses of a compound at levels lower than those required to achievethe desired therapeutic effect and to gradually increase the dosageuntil the desired effect is achieved. If desired, the effective dailydose can be divided into multiple doses for purposes of administration.Consequently, single dose compositions can contain such amounts orsubmultiples thereof to make up the daily dose. The dosage can beadjusted by the individual physician in the event of anycontraindications. Dosage can vary, and can be administered in one ormore dose administrations daily, for one or several days. Guidance canbe found in the literature for appropriate dosages for given classes ofpharmaceutical products. In further various aspects, a preparation canbe administered in a “prophylactically effective amount”; that is, anamount effective for prevention of a disease or condition.

As used herein, “kit” means a collection of at least two componentsconstituting the kit. Together, the components constitute a functionalunit for a given purpose. Individual member components may be physicallypackaged together or separately.

As used herein, “EC₅₀,” is intended to refer to the concentration of asubstance (e.g., a compound or a drug) that is required for 50%activation or enhancement of a biological process, or component of aprocess, including a protein, subunit, organelle, ribonucleoprotein,etc. For example, EC₅₀ can refer to the concentration of agonist thatprovokes a response halfway between the baseline and maximum response inan in vitro assay. Such in vitro assay systems frequently utilize a cellline that either expresses endogenously a target of interest, or hasbeen transfected with a suitable expression vector that directsexpression of a recombinant form of the target. For example, the EC₅₀for mAChR M₁ can be determined using Chinese hamster ovary (CHO-K1)cells transfected with human mAChR M₁. Alternatively, the EC₅₀ for mAChRM₁ can be determined using Chinese hamster ovary (CHO-K1) cellstransfected with rat mAChR M₁. In another example, the EC₅₀ for mAChR M₁can be determined using Chinese hamster ovary (CHO-K1) cells transfectedwith a mammalian mAChR M₁.

As used herein, “IC₅₀,” is intended to refer to the concentration of asubstance (e.g., a compound or a drug) that is required for 50%inhibition of a biological process, or component of a process, includinga protein, subunit, organelle, ribonucleoprotein, etc. For example, IC₅₀refers to the half maximal (50%) inhibitory concentration (IC) of asubstance as determined in a suitable assay. For example, an IC₅₀ formAChR M₁ receptor can be determined in an in vitro assay system.Frequently, receptor assays, including suitable assays for mAChR M₁,make use of a suitable cell-line, e.g. a cell line that either expressesendogenously a target of interest, or has been transfected with asuitable expression vector that directs expression of a recombinant formof the target such as mAChR M₁. For example, the IC₅₀ for mAChR M₁ canbe determined using Chinese hamster ovary (CHO-K1) cells transfectedwith human mAChR M₁. Alternatively, the IC₅₀ for mAChR M₁ can bedetermined using Chinese hamster ovary (CHO-K1) cells transfected withrat mAChR M₁.

Proper fluidity can be maintained,for example, by the use of coating materials such as lecithin, by themaintenance of the required particle size in the case of dispersions andby the use of surfactants. These compositions can also contain adjuvantssuch as preservatives, wetting agents, emulsifying agents and dispersingagents. Prevention of the action of microorganisms can be ensured by theinclusion of various antibacterial and antifungal agents such asparaben, chlorobutanol, phenol, sorbic acid and the like. It can also bedesirable to include isotonic agents such as sugars, sodium chloride andthe like. Prolonged absorption of the injectable pharmaceutical form canbe brought about by the inclusion of agents, such as aluminummonostearate and gelatin, which delay absorption. Injectable depot formsare made by forming microencapsule matrices of the drug in biodegradablepolymers such as polylactide-polyglycolide, poly(orthoesters) andpoly(anhydrides). Depending upon the ratio of drug to polymer and thenature of the particular polymer employed, the rate of drug release canbe controlled. Depot injectable formulations are also prepared byentrapping the drug in liposomes or microemulsions which are compatiblewith body tissues. The injectable formulations can be sterilized, forexample, by filtration through a bacterial-retaining filter or byincorporating sterilizing agents in the form of sterile solidcompositions which can be dissolved or dispersed in sterile water orother sterile injectable media just prior to use. Suitable inertcarriers can include sugars such as lactose.

The permissible substituents can beone or more and the same or different for appropriate organic compounds.For purposes of this disclosure, the heteroatoms, such as nitrogen, canhave hydrogen substituents and/or any permissible substituents oforganic compounds described herein which satisfy the valences of theheteroatoms. This disclosure is not intended to be limited in any mannerby the permissible substituents of organic compounds. Also, the terms“substitution” or “substituted with” include the implicit proviso thatsuch substitution is in accordance with permitted valence of thesubstituted atom and the substituent, and that the substitution resultsin a stable compound, e.g., a compound that does not spontaneouslyundergo transformation such as by rearrangement, cyclization,elimination, etc. It is also contemplated that, in certain aspects,unless expressly indicated to the contrary, individual substituents canbe further optionally substituted (i.e., further substituted orunsubstituted).

In defining various terms, “A¹,” “A²,” “A³,” and “A⁴” are used herein asgeneric symbols to represent various specific substituents.

Examples of suitable leavinggroups include halides and sulfonate esters, including, but not limitedto, triflate, mesylate, tosylate, brosylate, and halides.

The terms “hydrolysable group” and “hydrolysable moiety” refer to afunctional group capable of undergoing hydrolysis, e.g., under basic oracidic conditions. Examples of hydrolysable residues include, withoutlimitation, acid halides, activated carboxylic acids, and variousprotecting groups known in the art (see, for example, “Protective Groupsin Organic Synthesis,” T. W. Greene, P. G. M. Wuts, Wiley-Interscience,1999).

The term “organic residue” defines a carbon containing residue, i.e., aresidue comprising at least one carbon atom, and includes but is notlimited to the carbon-containing groups, residues, or radicals definedhereinabove. Organic residues can contain various heteroatoms, or bebonded to another molecule through a heteroatom, including oxygen,nitrogen, sulfur, phosphorus, or the like. Examples of organic residuesinclude but are not limited alkyl or substituted alkyls, alkoxy orsubstituted alkoxy, mono or di-substituted amino, amide groups, etc.Organic residues can preferably comprise 1 to 18 carbon atoms, 1 to 15,carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, 1 to 6 carbonatoms, or 1 to 4 carbon atoms. In a further aspect, an organic residuecan comprise 2 to 18 carbon atoms, 2 to 15, carbon atoms, 2 to 12 carbonatoms, 2 to 8 carbon atoms, 2 to 4 carbon atoms, or 2 to 4 carbon atoms.

A very close synonym of the term “residue” is the term “radical,” whichas used in the specification and concluding claims, refers to afragment, group, or substructure of a molecule described herein,regardless of how the molecule is prepared. For example, a2,4-thiazolidinedione radical in a particular compound has thestructure:

regardless of whether thiazolidinedione is used to prepare the compound.In some embodiments the radical (for example an alkyl) can be furthermodified (i.e., substituted alkyl) by having bonded thereto one or more“substituent radicals.” The number of atoms in a given radical is notcritical to the present invention unless it is indicated to the contraryelsewhere herein.

“Organic radicals,” as the term is defined and used herein, contain oneor more carbon atoms. An organic radical can have, for example, 1-26carbon atoms, 1-18 carbon atoms, 1-12 carbon atoms, 1-8 carbon atoms,1-6 carbon atoms, or 1-4 carbon atoms. In a further aspect, an organicradical can have 2-26 carbon atoms, 2-18 carbon atoms, 2-12 carbonatoms, 2-8 carbon atoms, 2-6 carbon atoms, or 2-4 carbon atoms. Organicradicals often have hydrogen bound to at least some of the carbon atomsof the organic radical. One example, of an organic radical thatcomprises no inorganic atoms is a 5, 6, 7, 8-tetrahydro-2-naphthylradical. In some embodiments, an organic radical can contain 1-10inorganic heteroatoms bound thereto or therein, including halogens,oxygen, sulfur, nitrogen, phosphorus, and the like. Examples of organicradicals include but are not limited to an alkyl, substituted alkyl,cycloalkyl, substituted cycloalkyl, mono-substituted amino,di-substituted amino, acyloxy, cyano, carboxy, carboalkoxy,alkylcarboxamide, substituted alkylcarboxamide, dialkylcarboxamide,substituted dialkylcarboxamide, alkylsulfonyl, alkylsulfinyl, thioalkyl,thiohaloalkyl, alkoxy, substituted alkoxy, haloalkyl, haloalkoxy, aryl,substituted aryl, heteroaryl, heterocyclic, or substituted heterocyclicradicals, wherein the terms are defined elsewhere herein. A fewnon-limiting examples of organic radicals that include heteroatomsinclude alkoxy radicals, trifluoromethoxy radicals, acetoxy radicals,dimethylamino radicals and the like.

“Inorganic radicals,” as the term is defined and used herein, contain nocarbon atoms and therefore comprise only atoms other than carbon.Inorganic radicals comprise bonded combinations of atoms selected fromhydrogen, nitrogen, oxygen, silicon, phosphorus, sulfur, selenium, andhalogens such as fluorine, chlorine, bromine, and iodine, which can bepresent individually or bonded together in their chemically stablecombinations. Inorganic radicals have 10 or fewer, or preferably one tosix or one to four inorganic atoms as listed above bonded together.Examples of inorganic radicals include, but not limited to, amino,hydroxy, halogens, nitro, thiol, sulfate, phosphate, and like commonlyknown inorganic radicals. The inorganic radicals do not have bondedtherein the metallic elements of the periodic table (such as the alkalimetals, alkaline earth metals, transition metals, lanthanide metals, oractinide metals), although such metal ions can sometimes serve as apharmaceutically acceptable cation for anionic inorganic radicals suchas a sulfate, phosphate, or like anionic inorganic radical. Inorganicradicals do not comprise metalloids elements such as boron, aluminum,gallium, germanium, arsenic, tin, lead, or tellurium, or the noble gaselements, unless otherwise specifically indicated elsewhere herein.

Compounds described herein can contain one or more double bonds and,thus, potentially give rise to cis/trans (E/Z) isomers, as well as otherconformational isomers.

Unless stated to the contrary, the invention includes all such possibleisomers, as well as mixtures of such isomers.

Unless stated to the contrary, a formula with chemical bonds shown onlyas solid lines and not as wedges or dashed lines contemplates eachpossible isomer, e.g., each enantiomer and diastereomer, and a mixtureof isomers, such as a racemic or scalemic mixture. Compounds describedherein can contain one or more asymmetric centers and, thus, potentiallygive rise to diastereomers and optical isomers. Unless stated to thecontrary, the present invention includes all such possible diastereomersas well as their racemic mixtures, their substantially pure resolvedenantiomers, all possible geometric isomers, and pharmaceuticallyacceptable salts thereof. Mixtures of stereoisomers, as well as isolatedspecific stereoisomers, are also included. During the course of thesynthetic procedures used to prepare such compounds, or in usingracemization or epimerization procedures known to those skilled in theart, the products of such procedures can be a mixture of stereoisomers.

Many organic compounds exist in optically active forms having theability to rotate the plane of plane-polarized light. In describing anoptically active compound, the prefixes D and L or R and S are used todenote the absolute configuration of the molecule about its chiralcenter(s). The prefixes d and l or (+) and (−) are employed to designatethe sign of rotation of plane-polarized light by the compound, with (−)or meaning that the compound is levorotatory. A compound prefixed with(+) or d is dextrorotatory. For a given chemical structure, thesecompounds, called stereoisomers, are identical except that they arenon-superimposable mirror images of one another. A specific stereoisomercan also be referred to as an enantiomer, and a mixture of such isomersis often called an enantiomeric mixture. A 50:50 mixture of enantiomersis referred to as a racemic mixture. Many of the compounds describedherein can have one or more chiral centers and therefore can exist indifferent enantiomeric forms. If desired, a chiral carbon can bedesignated with an asterisk (*). When bonds to the chiral carbon aredepicted as straight lines in the disclosed formulas, it is understoodthat both the (R) and (S) configurations of the chiral carbon, and henceboth enantiomers and mixtures thereof, are embraced within the formula.As is used in the art, when it is desired to specify the absoluteconfiguration about a chiral carbon, one of the bonds to the chiralcarbon can be depicted as a wedge (bonds to atoms above the plane) andthe other can be depicted as a series or wedge of short parallel linesis (bonds to atoms below the plane). The Cahn-Inglod-Prelog system canbe used to assign the (R) or (S) configuration to a chiral carbon.

Compounds described herein comprise atoms in both their natural isotopicabundance and in non-natural abundance. The disclosed compounds can beisotopically-labeled or isotopically-substituted compounds identical tothose described, but for the fact that one or more atoms are replaced byan atom having an atomic mass or mass number different from the atomicmass or mass number typically found in nature. Examples of isotopes thatcan be incorporated into compounds of the invention include isotopes ofhydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine,such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³⁵S, ¹⁸F and ³⁶Cl,respectively. Compounds further comprise prodrugs thereof, andpharmaceutically acceptable salts of said compounds or of said prodrugswhich contain the aforementioned isotopes and/or other isotopes of otheratoms are within the scope of this invention. Certainisotopically-labeled compounds of the present invention, for examplethose into which radioactive isotopes such as ³H and ¹⁴C areincorporated, are useful in drug and/or substrate tissue distributionassays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes areparticularly preferred for their ease of preparation and detectability.Further, substitution with heavier isotopes such as deuterium, i.e., ²H,can afford certain therapeutic advantages resulting from greatermetabolic stability, for example increased in vivo half-life or reduceddosage requirements and, hence, may be preferred in some circumstances.Isotopically labeled compounds of the present invention and prodrugsthereof can generally be prepared by carrying out the procedures below,by substituting a readily available isotopically labeled reagent for anon-isotopically labeled reagent.

The compounds described in the invention can be present as a solvate. Insome cases, the solvent used to prepare the solvate is an aqueoussolution, and the solvate is then often referred to as a hydrate. Thecompounds can be present as a hydrate, which can be obtained, forexample, by crystallization from a solvent or from aqueous solution. Inthis connection, one, two, three or any arbitrary number of solvate orwater molecules can combine with the compounds according to theinvention to form solvates and hydrates. Unless stated to the contrary,the invention includes all such possible solvates.

The term “co-crystal” means a physical association of two or moremolecules which owe their stability through non-covalent interaction.One or more components of this molecular complex provide a stableframework in the crystalline lattice. In certain instances, the guestmolecules are incorporated in the crystalline lattice as anhydrates orsolvates, see e.g. “Crystal Engineering of the Composition ofPharmaceutical Phases. Do Pharmaceutical Co-crystals Represent a NewPath to Improved Medicines?” Almarasson, O., et. al., The Royal Societyof Chemistry, 1889-1896, 2004. Examples of co-crystals includep-toluenesulfonic acid and benzenesulfonic acid.

It is also appreciated that certain compounds described herein can bepresent as an equilibrium of tautomers. For example, ketones with anα-hydrogen can exist in an equilibrium of the keto form and the enolform.

Likewise, amides with an N-hydrogen can exist in an equilibrium of theamide form and the imidic acid form. As another example, pyrazoles canexist in two tautomeric forms, N¹-unsubstituted, 3-R³ andN¹-unsubstituted, 5-R³ as shown below.

Unless stated to the contrary, the invention includes all such possibletautomers.

It is known that chemical substances form solids which are present indifferent states of order which are termed polymorphic forms ormodifications. The different modifications of a polymorphic substancecan differ greatly in their physical properties. The compounds accordingto the invention can be present in different polymorphic forms, with itbeing possible for particular modifications to be metastable. Unlessstated to the contrary, the invention includes all such possiblepolymorphic forms.

In some aspects, a structure of a compound can be represented by aformula:

which is understood to be equivalent to a formula:

wherein n is typically an integer. That is, R^(n) is understood torepresent five independent substituents, R^(n(a)), R^(n(b)), R^(n(c)),R^(n(d)), and R^(n(e)). By “independent substituents,” it is meant thateach R substituent can be independently defined. For example, if in oneinstance R^(n(a)) is halogen, then R^(n(b)) is not necessarily halogenin that instance.

For example,the starting materials and reagents used in preparing the disclosedcompounds and compositions are either available from commercialsuppliers such as Aldrich Chemical Co., (Milwaukee, Wis.), AcrosOrganics (Morris Plains, N.J.), Fisher Scientific (Pittsburgh, Pa.), orSigma (St. Louis, Mo.) or are prepared by methods known to those skilledin the art following procedures set forth in references such as Fieserand Fieser's Reagents for Organic Synthesis, Volumes 1-17 (John Wileyand Sons, 1991); Rodd's Chemistry of Carbon Compounds, Volumes 1-5 andSupplementals (Elsevier Science Publishers, 1989); Organic Reactions,Volumes 1-40 (John Wiley and Sons, 1991); March's Advanced OrganicChemistry, (John Wiley and Sons, 4th Edition); and Larock'sComprehensive Organic Transformations (VCH Publishers Inc., 1989).

Unless otherwise expressly stated, it is in no way intended that anymethod set forth herein be construed as requiring that its steps beperformed in a specific order. Accordingly, where a method claim doesnot actually recite an order to be followed by its steps or it is nototherwise specifically stated in the claims or descriptions that thesteps are to be limited to a specific order, it is no way intended thatan order be inferred, in any respect. This holds for any possiblenon-express basis for interpretation, including: matters of logic withrespect to arrangement of steps or operational flow; plain meaningderived from grammatical organization or punctuation; and the number ortype of embodiments described in the specification.

3. Muscarinic Acetylcholine Receptor M₁ Modulation

The human muscarinic acetylcholine receptor M₁(mAChR M₁) is a protein of479 amino acids encoded by the CHRM1 gene. The molecular weight of theunglycosylated protein is about 51,421 kDa and it is a transmembraneGPCR. As described above, the mAChR M₁ is a member of the GPCR Class 1family, or the rhodopsin-like GPCRs, which are characterized bystructural features similar to rhodopsin such as seven transmembranesegments. The muscarinic acetylcholine receptors have the N-terminusoriented to the extracellular face of the membrane and the C-terminuslocated on the cytoplasmic face. The orthosteric binding for naturalligand, acetylcholine, for mAChRs is believed to be located within apocket located within the transmembrane segments. The binding of ligandsto the orthosteric and allosteric sites can be distinguished usingmethods such as those described herein and a variety of other methodsknown to one skilled in the art.

In one aspect, the disclosed compounds potentiate the agonist response(e.g., acetylcholine) of mAChR M₁. In a further aspect, the disclosedcompounds increase mAChR M₁ response to non-maximal concentrations ofagonist in the presence of compound compared to the response to agonistin the absence of compound. The potentiation of mAChR M₁ activity can bedemonstrated by methodology known in the art. For example, activation ofmAChR M₁ activity can be determined by measurement of calcium flux inresponse to agonist, e.g. acetylcholine, in cells loaded with aCa²⁺-sensitive fluorescent dye (e.g., Fluo-4). In a further aspect, thecalcium flux was measured as an increase in fluorescent static ratio. Ina yet further aspect, positive allosteric modulator activity wasanalyzed as a concentration-dependent increase in the EC₂₀ acetylcholineresponse (i.e. the response of mAChR M₁ at a concentration ofacetylcholine that yields 20% of the maximal response).

In one aspect, the disclosed compounds activate mAChR M₁ response as anincrease in calcium fluorescence in mAChR M₁-transfected CHO-K1 cells inthe presence of the compound, compared to the response of equivalentCHO-K1 cells in the absence of the compound. For example, a disclosedcompound can have an EC₅₀ of less than about 10 μM, of less than about 5μM, of less than about 2.5 μM, of less than about 1 μM, of less thanabout 500 nM, of less than about 250 nM, of less than about 100 nM, orof less than about 50 nM. In a further aspect, the mAChR M₁-transfectedCHO-K1 cells are transfected with human mAChR M₁. In a still furtheraspect, the mAChR M₁-transfected CHO-K1 cells are transfected with ratmAChR M₁.

In one aspect, the disclosed compounds exhibit potentiation of mAChR M₁response to acetylcholine as an increase in response to non-maximalconcentrations of acetylcholine in CHO-K1 cells transfected with amammalian mAChR M₁ in the presence of the compound, compared to theresponse to acetylcholine in the absence of the compound. For example,CHO-K1 cells can be transfected with human mAChR M₁. For example, CHO-K1cells can be transfected with rat mAChR M₁. For example, a compound canexhibit positive allosteric modulation of mAChR M₁ with an EC₅₀ of lessthan about 10,000 nM, of less than about 5,000 nM, of less than about2,500 nM, of less than about 1,000 nM, of less than about 500 nM, ofless than about 250 nM, or of less than about 100 nM. Alternatively, thedisclosed compounds exhibit potentiation of mAChR M₁ response toacetylcholine as an increase in response to non-maximal concentrationsof acetylcholine in CHO-K1 cells transfected with human mAChR M₁ in thepresence of the compound, compared to the response to acetylcholine inthe absence of the compound. For example, a compound can exhibitpositive allosteric modulation of mAChR M₁ with an EC₅₀ of less thanabout 10,000 nM, of less than about 5,000 nM. of less than about 2,500nM, of less than about 1,000 nM, of less than about 500 nM, of less thanabout 250 nM, of less than about 100 nM, or of less than about 50 nM.

In one aspect, the disclosed compounds are positive allostericmodulators of the mAChR M₁. Thus, the compounds of the invention canbind to the muscarinic receptor, and particularly to muscarinic receptorsubtype M₁, which results in an increased efficacy at that receptor forthe endogenous agonist. Thus, by positive allosteric modulation, thecompounds indirectly activate the muscarinic receptor subtype M₁. Invarious further aspects, the disclosed compounds exhibit positiveallosteric modulation of mAChR M₁ response to acetylcholine as anincrease in response to non-maximal concentrations of acetylcholine inCHO-K1 cells transfected with a mAChR M₁ in the presence of thecompound, compared to the response to acetylcholine in the absence ofthe compound. In a yet further aspect, the disclosed compounds exhibitpositive allosteric modulation of the mAChR M₁ response to acetylcholinewith an EC₅₀ of less than about 10,000 nM. In an even further aspect,the disclosed compounds exhibit positive allosteric modulation of themAChR M₁ response to acetylcholine with an EC₅₀ of less than about 5,000nM. In a yet further aspect, the disclosed compounds exhibit positiveallosteric modulation of the mAChR M₁ response to acetylcholine with anEC₅₀ of less than about 2,500 nM. In a still further aspect, thedisclosed compounds exhibit positive allosteric modulation of the mAChRM₁ response to acetylcholine with an EC₅₀ of less than about 1,000 nM.In a yet further aspect, the disclosed compounds exhibit positiveallosteric modulation of the mAChR M₁ response to acetylcholine with anEC₅₀ of less than about 500 nM. In a still further aspect, the disclosedcompounds exhibit positive allosteric modulation of the mAChR M₁response to acetylcholine with an EC₅₀ of less than about 250 nM. In aneven further aspect, the disclosed compounds exhibit positive allostericmodulation of the mAChR M₁ response to acetylcholine with an EC₅₀ ofless than about 100 nM. In a still further aspect, the EC₅₀ for positiveallosteric modulation is determined in CHO-K1 cells are transfected witha mAChR M₁. In a yet further aspect, the CHO-K1 cells are transfectedwith a human mAChR M₁. In a still further aspect, the CHO-K1 cells aretransfected with a rat mAChR M₁.

Without wishing to be bound by a particular theory, the disclosedcompounds and products of the disclosed methods are believed to bind toan allosteric site distinct from the orthosteric binding site. Further,without wishing to be bound by particular theory, the disclosedcompounds and products of the disclosed methods can bind to anallosteric site that comprises portions of one or more extracellularloops and/or transmembrane segments, and is distinct from theorthosteric binding site. In a further aspect, without wishing to bebound by a particular theory, the disclosed compounds and products ofthe disclosed methods can bind to an allosteric site that comprisesportions of one or more intracellular loops and/or transmembranesegments, and is distinct from the orthosteric binding site. In a stillfurther aspect, without wishing to be bound by particular theory, thedisclosed compounds and products of the disclosed methods can bind to anallosteric site that comprises portions of segments, amino acids, orsub-domains of the mAChR M₁ protein that potentiates interactions of theprotein with other proteins, e.g. G-proteins.

Previous attempts to develop agonists that are highly selective forindividual mAChR subtypes have failed because of the high conservationof the orthosteric ACh binding site. To circumvent problems associatedwith targeting the highly conserved orthosteric ACh binding site, it isbelieved that developing compounds that act at less highly conservedallosteric mAChR sites will afford highly selectiveactivators/modulators.

In various further aspects, the compound activates mAChR M₁ response inmAChR M₁-transfected CHO-K1 cells with an EC₅₀ less than the EC₅₀ forone or more of mAChR M₂, mAChR M₃, mAChR M₄, or mAChR M₅ response inmAChR M₂, M₃, M₄ or M₅-transfected CHO-K1 cells.

8. Cell Lines Expressing Muscarinic Acetylcholine Receptors

Chinese hamster ovary (CHO-K1) cells stably expressing rat (r)M₁ werepurchased from the American Type Culture Collection and culturedaccording to their indicated protocol. CHO cells stably expressing human(h)M₂, hM₃, and hM₅ were described previously (Levey, et al., 1991); hM₁and hM₄ cDNAs were purchased from Missouri S&T cDNA Resource; rM₄ cDNAwas provided by T. I. Bonner (National Institutes of Health, Bethesda,Md.). rM₂ and rM₃ were cloned from a rat brain cDNA library and sequenceverified. hM₁, rM₂, rM₃, hM₄, and rM₄ cDNAs were used to stablytransfect CHO-K1 cells purchased from the American Type CultureCollection using Lipofectamine2000. To make stable rM₂, hM₂, rM₃, hM₄,and rM₄ cell lines for use in calcium mobilization assays, these cellsalso were stably transfected with a chimeric G-protein (G_(qi5))(provided by B. R. Conklin, University of California, San Francisco)using Lipofectamine 2000. rM₁, hM₁, rM₃, hM₃, rM₅, and hM₅ cells weregrown in Ham's F-12 medium containing 10% heat-inactivated fetal bovineserum (FBS), 20 mM HEPES, and 50 μg/mL G418 sulfate. rM2-G_(qi5),hM₂-G_(qi5), and hM₄-G_(qi5) cells were grown in the same medium alsocontaining 500 μg/mL Hygromycin B. Stable rM₄-G_(qi5) cells were grownin DMEM containing 10% heat-inactivated FBS, 20 mM HEPES, 400 μg/mL G418sulfate, and 500 μg/mL Hygromycin B.

9. Cell-Based Functional Assay of Muscarinic Acetylcholine ReceptorActivity

For high throughput measurement of agonist-evoked increases inintracellular calcium, CHO-K1 cells stably expressing muscarinicreceptors were plated in growth medium lacking G418 and hygromycin at15,000 cells/20 μL/well in Greiner 384-well black-walled, tissue culture(TC)-treated, clear-bottom plates (VWR). Cells were incubated overnightat 37° C. and 5% CO₂. The next day, cells were washed using an ELX 405(BioTek) with four washes (80 μL) of assay buffer then aspirated to 20μL. Next, 20 μL of 16 μM Fluo-4/acetoxymethyl ester (Invitrogen,Carlsbad, Calif.) prepared as a 2.3 mM stock in DMSO and mixed in a 1:1ratio with 10% (w/v) Pluronic F-127 and diluted in assay buffer wasadded to the wells and the cell plates were incubated for 50 min at 37°C. and 5% CO₂. Dye was removed by washing with the ELX 405 (four 80 μLwashes of assay buffer) then aspirated to 20 μL. Compound master plateswere formatted in an 11 point CRC format (1:3 dilutions) in 100% DMSOwith a starting concentration of 10 mM using the BRAVO liquid handler(Agilent). Test compound CRCs were then transferred to daughter plates(240 nL) using the Echo acoustic plate reformatter (Labcyte, Sunnyvale,Calif.) and then diluted into assay buffer (40 μL) to a 2× stock using aThermo Fisher Combi (Thermo Fisher Scientific, Waltham, Mass.).

Calcium flux was measured using the Functional Drug Screening System(FDSS) 6000 (Hamamatsu Corporation, Tokyo, Japan) as an increase in thefluorescent static ratio. Compounds were applied to cells (20 μL, 2×)using the automated system of the FDSS 6000 at 4 s into the 300 sprotocol and the data were collected at 1 Hz. At 144 s into the 300 sprotocol, 10 μL of an EC₂₀ concentration of the muscarinic receptoragonist acetylcholine was added (5×), followed by the addition of 12 μLan EC₈₀ concentration of acetylcholine at the 230 s time point (5×).Agonist activity was analyzed as a concentration-dependent increase incalcium mobilization upon compound addition. Positive allostericmodulator activity was analyzed as a concentration-dependent increase inthe EC₂₀ acetylcholine response. Antagonist activity was analyzed as aconcentration-dependent decrease in the EC₈₀ acetylcholine response.Concentration-response curves were generated using a four-parameterlogistical equation in XLfit curve fitting software (IDBS, Bridgewater,N.J.) for Excel (Microsoft, Redmond, Wash.) or Prism (GraphPad Software,Inc., San Diego, Calif.).

The above described assay was also operated in a second mode where anappropriate fixed concentration of the present compounds were added tothe cells after establishment of a fluorescence baseline for about 3seconds, and the response in cells was measured. 140 s later theappropriate concentration of agonist was added and readings taken for anadditional 106 s. Data were reduced as described above and the EC₅₀values for the agonist in the presence of test compound were determinedby nonlinear curve fitting. A decrease in the EC₅₀ value of the agonistwith increasing concentrations of the present compounds (a leftwardshift of the agonist concentration-response curve) is an indication ofthe degree of muscarinic positive allosteric modulation at a givenconcentration of the present compound. An increase in the EC₅₀ value ofthe agonist with increasing concentrations of the present compounds (arightward shift of the agonist concentration response curve) is anindication of the degree of muscarinic antagonism at a givenconcentration of the present compound. The second mode also indicateswhether the present compounds also affect the maximum response of themuscarinic receptor to agonists.

The calcium mobilization assay was also used to determine “efficacy”. Inthe context of the assays carried out for the data in Table II,“efficacy” (% ACh at 30 μM) is defined as the maximal response in thecalcium flux as determined by the sigmoidal curve fit of theconcentration response curve, or in the absence of an acceptable curvefit, the response recorded at 30 μM test compound, stated as apercentage of the response elicited by a concentration of Ach thatinduces approximately 80% of a maximal (i.e. saturating) ACh response.
